ITECH IT7803-350-30

Overview

Adopting advanced SiC technology，ITECH IT7800 3U high series of programmable AC/DC power supply, with power up to 15kVA, voltage ranges up to 350V L-N. Users are able to increase output power up to 960kVA by configuring master-slave parallel. With intuitive LCD touch panel interface, users can be quickly familiar with the unit operation. IT7800 series is built-in power meter and arbitrary waveform generator, which is able to simulate harmonics and other arbitrary waveform output. Users can choose single phase, three-phase, reverse phase, and multi-channel totally 4 output modes, with programmable output, and complete measurements, ITECH IT7800 series is designed for new energy, power electronics, research institutes etc.

Constant Current source mode

The IT7800 series has a current source mode. It can operate in various modes such as single-phase, reverse phase, AC and AC+DC. Its maximum voltage can reach 700V, which can meet various high voltage and high current applications. Meanwhile, the Normal and LIST functions can cope with various types of conventional and dynamic testing requirements. The rich waveform editing and customization functions can also help you simulate complex current waveforms. Current source mode can provide stable current output so that you can simulate various loads, such as laser drivers, LEDs, motors, etc. It can quickly do frequency sweep, charge/discharge, AC impedance and other related tests on various types of batteries. While improving test efficiency and accuracy, the IT7800 also optimizes the system design while ensuring safety.

Multi-channel function

The multi-channel function of the IT7800 series allows users to test 3 independent DUT at the same time without adding additional hardware configuration. In the traditional solution, 3 tests for the DUT, the user needs to configure 3 AC power supplies; and one IT7800 device can meet multi-channel testing requirements. For example, IT7815-350-90 rated power is 15kVA, can provide single-phase/three-phase 15kVA DUT test, can also meet up to 3* single-phase DUT test, one machine with multiple functions, fully improves the equipment utilization.

AC, DC、AC+DC、DC+AC

The IT7800 series has four output modes: AC, DC, AC+DC, DC+AC. It not only provides pure AC/DC output, but also can use AC+DC and DC+AC output modes to realize "AC output plus DC bias" And "DC output waveform with ripple", which cover a wider range of applications.

Single phase, three phase, reverse phase

The IT7800 series provides multiple output modes such as single-phase, three-phase and reverse phase, which can be selected by the user through the panel menu. By programming ,it can simulate three-phase unbalance, three-phase harmonic unbalance, lack of phase test, phase sequence reverse connection and other tests, which are flexible and cover more applications. At the same time, IT7800's reverse mode can also provide a high-voltage test solution. Its voltage can be increased to twice and the power remains 2/3.
For example, if it is set to 350V, the actual output voltage can reach 700V after the reverse mode is selected.

Harmonic analysis and simulation

The harmonic analysis function of IT7800 series includes voltage harmonic measurement and current harmonic measurement. In the harmonic mode, the voltage and current harmonic distortion factor (THD) and the phase difference of the harmonic to the fundamental wave can be tested. In addition, it can measure multiple harmonics, and the results are displayed in a list, histogram or vector diagram, making the test results easy to be seen.
